Description

Speed guidance system

The present invention relates to a guidance system, and more particularly to a vehicle speed guidance system capable of guiding a vehicle in motion to remain within a speed limit range.

The driving speed of vehicles has different speed limit requirements in urban areas and suburbs or on expressways. Even in different sections of urban areas, there are different speed limit requirements. Therefore, for every law-abiding driver, Comply with the relevant speed limit regulations. However, the driver can see the speed of the driving vehicle from the dashboard while driving, in order to meet the requirements of the lower speed, but it is not very convenient after all, because sometimes it is difficult to know the speed limit of the road that is driving. Often, they often accidentally overspeed and receive red orders. What's more, drivers who are driving in limited speed tunnels (such as snow tunnels) should concentrate more on them. Otherwise, it is easier for traffic caused by turtle speed to run smoothly. However, for the driver, on the one hand, the eyes must pay attention to the dashboard inside the vehicle. On the other hand, it is necessary to pay attention to the speed of the front, and the probability of distraction is very high. In view of this, it is indeed necessary to actively improve driving to help drivers maintain smooth driving.

It is an object of the present invention to provide a vehicle speed guidance system capable of projecting the same limited speed moving light on the front side of the vehicle at each speed limit section, thereby providing a driver with direct visibility and intuitive vehicle Whether the moving light travels at the same speed can avoid the traffic that is not smooth due to speeding or turtle driving.

In order to achieve the above object, the vehicle speed guiding system of the present invention comprises: a microprocessor and a guiding unit, the micro processing comprises a memory and a transmission control unit, and the memory body prestores at least a location with a speed limit road section and a speed limit requirement; The transmission control unit is connected to the memory, and can continuously transmit the pre-stored message of the memory to the guiding unit at a speed equal to the location and the speed limit according to the location, the speed limit, and the like; the guiding unit The laser is included to transmit the transmitted laser light to the front side of the vehicle, such as the transmitted location and the speed limit. If so, the driver can directly view and intuitively detect whether the vehicle and the moving laser light are Drive at the same speed and adjust the speed.

According to the above, the microprocessor further pre-stores the warning text (for example, maintaining the vehicle speed) to remind the driver of the moving light and the text.

The first figure is a block flow diagram of the vehicle speed guiding system of the present invention.

The second and third figures are schematic diagrams of the implementation of the vehicle speed guidance system of the present invention in a tunnel.

Referring to the first figure, the vehicle speed guiding system 1 of the present invention comprises: a microprocessor 2 and a guiding unit 3, wherein the microprocessor 2 comprises: a memory 21 and a transmission control unit 22, and the memory 21 is pre-stored. Speed section location and speed limit requirements (for example: school speed limit of 40 km/h, hospital speed limit of 30 km/h, highway speed limit of 100 km/h, snow mountain tunnel speed limit of 70 km/h) and warning text (such as maintaining speed, keeping The transmission control unit 22 is connected to the memory 21, and can transmit the pre-stored message of the memory 21 to the guiding unit 3 at a speed equal to the location and the speed limit according to the location, the speed limit, and the like. .

The guiding unit 3 can use a laser or an LED lamp to transmit the information of the location, the speed limit and the distance of the vehicle transmitted by the transmission control unit 22, and the moving light source and the text are projected on the driver's direct view or the remaining light of the eye. Wherever possible, the best angle is preferably projected on the front side of the vehicle's travel, and a contrasting color that can be highlighted can be selected depending on the projected background.

Please refer to the second figure in conjunction with the first figure, which is a schematic diagram of the vehicle speed guiding system implemented in the Xueshan tunnel. As shown in the figure, the vehicle speed guiding system 1 is disposed near the tunnel, and the memory 21 prestores the snow mountain. The speed limit of the tunnel is 70 km/h, and the transmission control unit 22 continuously transmits the 70 km-speed information of the snow-capped tunnel to the guiding unit 3 at a speed equal to the speed of the point and the speed limit. The guiding unit 3 (this embodiment) The laser light source is continuously projected on the front side of the vehicle traveling with the moving light source. At this time, the driver of the vehicle 5 drives the vehicle at the same speed with the direct light or the residual light of the eyes, if the vehicle speed is at the same speed. Below or above the speed at which the guiding unit 3 continues to transmit, the driver can adjust the speed of the speed, and the effect of avoiding the traffic caused by the speeding or the turtle speed driving can be avoided. Similarly, referring to the third figure, the guiding unit 3 continuously projects on the front side of the vehicle traveling with the moving light source displaying the words "holding the vehicle speed and maintaining the vehicle distance", and the driver of the vehicle 5 takes direct vision or the residual light of the eyes. You can see the moving light source and related warnings, in addition to adjusting the speed of the vehicle and maintaining the distance between the vehicle and the preceding vehicle. If it can achieve the effect of avoiding speeding and turtle driving.

In summary, the vehicle speed guiding system of the present invention can achieve the object of the invention, and meets the requirements of the patent, but the above is only the preferred embodiment of the present invention, and various modifications and changes according to the present invention are still It should be included in the scope of this patent application.
